content, since it may represent methane that will not readily flow to a methane drainage borehole under field conditions. Residual gas may also represent a portion of the total gas content that will not be admitted into a mine atmosphere either from migration to the mine openings from the surrounding coal or from the mining of the coal at the face.
Whatever gas is in the coal, the majority of it is released as, or soon after, the coal is cut. With the high rate of production in modern coal mines, there are many loions where the amount of gas released is too great for the mine ventilation system to keep gas concentrations at or below acceptable levels.
